In-cable control and protection device (IC-CPD) for mode 2 charging of electric road vehicles
IEC 62752:2024 This International Standard applies to in-cable control and protection devices (IC-CPDs) for mode 2 charging of electric road vehicles, hereafter referred to as "IC-CPD", including control and safety functions. This document applies to portable devices performing simultaneously the functions of detection of the residual current, of comparison of the value of this current with the residual operating value and of opening of the protected circuit when the residual current exceeds this value. This second edition cancels and replaces the first edition published in 2016, and Amendment 1:2018. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - Subclause 8.3.1 revised to add requirements for a mandatory control device that detects the temperature of the current carrying parts in the household plug; - Test requirements added in a new Subclause 9.36 for the temperature control device; - Harmonization of EMC requirements with new edition of IEC 61543 and IEC 61851-21-2; - General improvement of test and requirements.
Ladeleitungsintegrierte Steuer- und Schutzeinrichtung für die Ladebetriebsart 2 von Elektro-Straßenfahrzeugen (IC-CPD)
Dispositif de contrôle et de protection intégré au câble (IC-CPD) pour la charge en mode 2 des véhicules électriques
L'IEC 62752:2024 s'applique aux dispositifs de contrôle et de protection intégrés au câble (IC-CPD) pour la charge en mode 2 des véhicules électriques, ci-après dénommés "IC‑CPD", y compris les fonctions de commande et de sécurité. Le présent document s'applique aux dispositifs portables qui remplissent à la fois les fonctions de détection du courant différentiel résiduel, de comparaison de la valeur de ce courant à une valeur de fonctionnement différentiel et d'ouverture du circuit protégé lorsque le courant différentiel résiduel dépasse cette valeur. Cette deuxième édition annule et remplace la première édition parue en 2016 et son Amendement 1:2018. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - révision du 8.3.1 afin d'ajouter des exigences pour un dispositif de commande obligatoire qui détecte la température des parties parcourues par un courant dans la fiche pour usages domestiques; - ajout d'exigences d'essai dans un nouveau paragraphe 9.36 pour le dispositif de commande thermique; - harmonisation des exigences de compatibilité électromagnétique (CEM) par rapport à la nouvelle édition de l'IEC 61543 et à l'IEC 61851‑21‑2; - amélioration générale de l'essai et des exigences associées.
Integrirana zaščita kabla in zaščitna naprava tipa 2 za napajanje električnih cestnih vozil (IC-CPD) (IEC 62752:2024)
Ta mednarodni standard se uporablja za integrirane zaščite kablov in zaščitne naprave (IC-CPD) tipa 2 za napajanje električnih cestnih vozil, v nadaljnjem besedilu »IC-CPD«, vključno z nadzornimi in zaščitnimi funkcijami.
Ta dokument se uporablja za prenosne naprave, ki hkrati izvajajo funkcije zaznavanja preostalega toka, primerjanja vrednosti tega toka s preostalo obratovalno vrednostjo in odprtja zaščitenega tokokroga, kadar preostali tok preseže to vrednost.
Integrirana zaščita kabla in zaščitna naprava v skladu s tem dokumentom:
• zagotavlja krmilni upravljalnik v skladu s standardom IEC 61851-1:2017, dodatek A;
• preverja pogoje napajanja in preprečuje napajanje v primeru napak pod določenimi pogoji;
• lahko vključuje zaščitni vodnik.
Obravnavani so preostali tokovi s frekvencami, različnimi od nazivne frekvence, enosmerni preostali tokovi in specifične okoljske razmere.
Ta dokument se uporablja za integrirane zaščite kablov in zaščitne naprave z varnostnimi in nadzornimi funkcijami, kot je zahtevano v standardu IEC 61851-1 za napajanje električnih vozil tipa 2.
Ta dokument se uporablja za integrirane zaščite kablov in zaščitne naprave za enofazne tokokroge, ki ne presegajo 250 V, ali za večfazne tokokroge, ki ne presegajo 480 V, pri čemer je njihov največji nazivni tok 32 A.
Ta dokument se uporablja za integrirane zaščite kablov in zaščitne naprave, ki se uporabljajo samo v izmeničnem tokokrogu, s priporočenimi vrednostmi frekvence 50 Hz, 60 Hz ali 50/60 Hz. Integrirane zaščite kablov in zaščitne naprave v skladu s tem dokumentom niso namenjene uporabi pri dvosmernem ali povratnem prenosu moči za povratek energije v sistem za distribucijo električne energije.
Ta dokument se uporablja za integrirane zaščite kablov in zaščitne naprave, katerih preostali tok ne presega 30 mA in ki so namenjene za dodatno zaščito tokokroga integrirane zaščite kablov in zaščitne naprave v smeri toka, ker ni mogoče zagotoviti, da je inštalacija proti toku opremljena z napravo na preostali tok z vrednostjo IΔn ≤ 30 mA.
Integrirana zaščita kabla in zaščitna naprava vključuje:
• vtič za povezavo z izhodno vtičnico fiksne inštalacije;
• enega ali več podsklopov, ki vsebujejo nadzorne in zaščitne funkcije;
• kabel med vtičem in podsklopi (izbirno);
• kabel med podsklopi in priključkom vozila (izbirno);
• priključek vozila za povezavo z električnim vozilom.
Za vtiče za gospodinjsko in podobno uporabo se uporabljajo zahteve nacionalnih standardov in specifične zahteve, ki jih je določil nacionalni komite države prodaje proizvoda. Če nacionalne zahteve ne obstajajo, se uporablja standard IEC 60884-1. Za industrijske vtiče se uporablja standard IEC 60309-2. Za specifične aplikacije in območja je mogoče uporabiti nezamenljive industrijske vtiče. V tem primeru se uporablja standard EN 60309-1.
Vtiči, priključki in kabli, ki so del integrirane zaščite kabla in zaščitne naprave, so preskušeni v skladu z ustreznimi standardi za proizvode.
Preklopni kontakti integrirane zaščite kabla in zaščitne naprave ne zagotavljajo izolacije, saj je to mogoče zagotoviti z izklopom vtiča.
Integrirana zaščita kabla in zaščitna naprava se ne šteje za zaščitno napravo, ki se uporablja v fiksnih inštalacijah.
